TH830A3 - Automatic backup vacuum generation system - Google Patents

Abstract

Automatic backup vacuum generation system It is a system that can create a vacuum automatically to replace the original vacuum from the engine to make the brake air booster. Can work normally When the engine is stopped and the driver needs to use the brakes. When the engine can run As usual, the system automatically generates a backup vacuum. It will stop creating a vacuum automatically. The original vacuum from the engine will replace it. Brake booster works as before. The brakes will have Same picture rights

Claims (3)

1.Automatic backup vacuum generating system includes - Vacuum generator. That can be powered by the car's battery Which creates a vacuum Reserve gas to the brake booster in case of engine failure. The vacuum generator is controlled. To work or stop working as well Electronic system controller It is characterized by that - one-way valve. Has two numbers By cutting and separating the vacuum hose from the brake booster into 2 pipes by using a three-way joint for the split. And to connect one one-way valve in The manner in which air can flow from the brake booster through the aforementioned one-way valves only in one direction. The remaining one-way valves are connected to the vacuum generator. In which both one-way valves act Separate the vacuum system obtained from the engine. And obtained from the vacuum generator to act independently of each other. - Electronic control system. Is a switch that works with a diffused electromagnetic field Coming out of the dichart Or a system of ignition to generate electromagnetic fields while the machine Motor running Where the electromagnetic field Will be induced to the magnetic field coil Which acts as a detector of the controller of the electronic system and is converted to electromotive force. To control the relay to operate When the engine is turned off, the electromagnetic field emitted by the dichart and From the ignition, there will be no. The electromagnetic field that will be induced at the coil or detector of the body. Electronic control system makes no force to feed the relay, which is connected in series with the brake light switch. Ready to order the vacuum generator to work 2. Automatic backup vacuum generation system According to claim 1, where when the engine vacuum is activated, the vacuum obtained from the vacuum generator is closed by a one-way valve and vice versa, if the resulting vacuum system From the working vacuum generator The engine vacuum. Was closed from work This can prevent the vacuum system from leaking. 3. Automatic backup vacuum generation system According to claim 1 or 2, where the electronic system controller Will detect the engine shutdown And the work of the brake light switch when the brake pedal is used to control the vacuum generator. When the engine stops and the brakes are pressed And will control himself The vacuum generator stops when the engine is stuck or the brake pedal is not depressed.
